I would be very disappointed if I paid $4000 for a professional grade printer to find a bunch of 3d printed upgrades all over the thing? Wouldn't it make more sense to develop the molded parts properly and release the new product line when it is ready for production?

The use of 3D printed parts in new products is becoming more and more common. Most Customers will not realize it, because there will be no impact on performance. This is the case, due to the hardware development process. To produce parts by injection molding or other traditional manufacturing processes, requires a long period of preparation that may be difficult to include in the very beginning of a new product. Therefore, what is called “bridge manufacturing” is becoming more common and helping companies, like Raise3D, to bring new products to market. By Pathfinding Flexible Manufacturing we want exactly to promote the value of bridge manufacturing as a way to shorten the new product launches’ cycles.

I just had a crazy question that was mostly spun from the Matterhackers video that was posted here in the thread. In that video, the castle they printed apparently took 15 days. So out of curiosity, is it possible for the Pro2 printers especially (since it has a filament sensor) to have the option when the first nozzle runs out of filament, for the second nozzle to take over printing where the first left off?

It's not a necessity or anything, really just a question that arose from the castle build in that video given the amount of time and the amount of filament that must have consumed.

If there is 3d printed parts made by Raise3d, I hope they will put more quality on the material used and a better external finish.Because I have seen ugly parts sometime in the past. And if we look on the pictures of the Pro2, I propose you put more quality on those parts, please. It would be great to share the stl files also, in case of people want to remake them.

This is an EXCELLENT idea, especially given the larger build volume!

I think this is also an excellent idea, but it could be hard to implement.

It could be quite difficult because of the nature of G-Code. It's a long string of absolute positions and discrete actions the print head is commanded to do, generated by the slicer, run by the printer from start to finish w/ out any sort of feedback loop or analysis of the state of the print or results of the last action.

You *might* be able to do this if you were to generate a second G-Code program for the other nozzle when you're doing the slicing, but it would still be challenging. You'd have to be able to guarantee that you could pick up with the other set of instructions exactly where you left off with the first set, accounting for path optimizations that the slicer might generate for one nozzle/head vs. the other. Your G-Code file would also be (approx, ) twice as big for every time you wanted to use this feature.

I had seen BCN3D Sigmax dual printing and I like the feature when dual printing, the unused nozzle will have temperature drop down to around 150-160c to minimized the oozing and kickback when it is about to switch back to do the printing. Though this might not work for Raise3D Pro2 as it is not Independent Extruder like Sigmax.

Ultimaker S5 come with various swap-able print heads and 2 types of print bed for different kinds of materials which I hope Raise3D can have something like this in the near future.

The 3D printer for prosumer look like the price is shooting upwards recently as more business customers try to adopt this technology whereas consumer/diy 3D printer price is hitting rock bottom.

As far as based on the current information we currently known on hand, the reason why Ultimaker has different types of swap-able print heads and print beds is for adapting different types of material. But the filament which are listed for Pro2 series have all passed with our standard extruder, nozzle and print surface. So we have no plan to develop different types of print heads and beds as ours can work properly with different filaments by default.

And, just commented on that video, there are 2 minor things in the video and voice over.First is a simple wording explanation of moving the Z axis to free the trapped box below it."Minor wording, you mean press the Z axis homing icon to move the Z axis to the origin (AKA homed position).﻿"Technically, on the LCD, we have had a grammatical error for a long time, the popup dialog is missing the word "to" origin. Really it should say something more informative to the new user, more like caution, about to move the Z axis table up, ensure bed is clear- that that's just a new suggestion altogether. I would think the video voice over might be better if it said the same thing, maybe even explain origin to the new user. I'm not saying go in depth, but again, just seeing how some of these terms are very CNC knowledge based, there is room for improvement if you are targeting this printer at a new audience of even less experienced users who demand it to "just work".

Second, when loading filament:Pro tip: Cut off the tip of your filament that you are loading as the video shows the bent end of the filament, most likely from shipping through the hole in the side of the spool to keep it unraveling. The idea here is that end whip of the filament is often brittle and the bend may prevent proper loading. This is pretty much standard advice for every 3D printer, and yet the video is showing bad habits to new users.﻿ This concern is even greater since you have to pass through the filament detection module and then still pray the filament loads into the new Bondtech feeder.
